Twist: the myth was the professor believing that to be a myth!
Also, it is indeed possible for contaminants to create a lung abscess with anaerobic conditions within. No idea regarding the frequency of such.
Lastly, not all of the alveolar tree is ventilated at all times, there are non-ventilated parts that do not even get perfusion (Euler-Liljestrand mechanism). Those could also provide a breeding ground for anaerobes.
You’re right about the abscesses, hence my statement, “In reality it takes frequent aspirations over a long period of time to block off an area of the lungs.” However, one aspiration usually won’t cause such a scenario.
